Their answer is correct so you need explanation?
Answer:
25x-49
Step-by-step explanation:
5x×5x=25x 5x×-7= -35x
7×5x=35x 7×-7=-49
(combine like terms)25x+-35x+35x= 25
hope that helped you!
Answer:
See below.
Step-by-step explanation:
a)
105/3 = 35
35/5 = 7
7/7 = 1
429/3 = 143
143/11 = 13
13/13 = 1
105 = 3 * 5 * 7
429 = 3 * 11 * 13
Not co-prime
For the other parts of the problem, do the same I did above. Find the prime factorizations of both numbers, and see if they have any prime factors in common.
